Secret's out: We enjoy hanging out with Mindless Behavior. The teen R&B-pop quartet knows how to a play a party bus, so it's no surprise they'd also know how to play a musical guessing game. (It's the next logical progression in hanging out, certainly.)

We tested the boys' musical acumen by playing six different songs and challenging them to guess the song and the artist as quickly as possible. We chose new songs and older songs—songs by their contemporaries, their influences, and artists they've worked with. We timed their guesses and continued to record their conversations as their mindless minds wandered. Look forward to a discussion of the term "swag," the Tooth Fairy's going rate, and the proper way to get someone to call you, definitely. Hint, hint.

Princeton: I literally just found out. My mom told me and I was like, "What're you talkin' bout, mom?!" I was all depressed! 15 years of happiness down the drain. The tooth fairy doesn't accept my rotten teeth.

Ray Ray: I never believed in the Easter bunny. I don't get the story. Why a bunny?

Prodigy.: One time I was pretending to sleep to see if the tooth fairy was real, and I felt my head lift up, and my mom was there.
